vWILLIAM D. LABADIE, OF SOUTH BEND, INDIANA.

ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 766,707, dated August2, 1904.

Application filed December 13, 1902. Serial No. 135,131. (No model.)

To all whom it may concern.-

Beit known that I, VVILLIAH D. LABADIE, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements in RotaryEngines; and I do hereby declare the followingto be a full, clear, andexact description of theinvention, such as will enable others skilled inthe art to which it appertainsto make and use the same.

This invention relates to rotary engines.

The object of the present invention is to provide a rotary duid-actuatedmotor of simple and inexpensive construction adapted to be employed as adriving means for rotary tools of diderent description, and moreespecially designed for use in connection with a rotary cuting-tool forremoving incrustation from tubes and flues.

The invention is illustrated in the accompanying drawings, in which-Figure l is a longitudinal section of the fluid-motor with the coneshown in side elevation. Fig. 2 is a plan View of the cone removed. Fig.3 is a detail view of the end of one of the nozzles. Fig. #L is a planview of the cutters assembled.

In carrying out the invention the driving mechanism for the cutters maybe arranged in any convenient form of casing; but the preferredembodiment is shown in Fig. l of the drawings, in which a casing l ofsubstantially cylindrical shape, having a closed semispherical lower end2 and an open upper end 3, is employed.

In the semispherical end is formed a substantially semicircular conduit4, having' a coupling' 5 between the ends thereof adapted to connectwith and permit the supply of motive power, which may be either water orair, preferably the former. The ends of the conduit terminate incontracted nozzles 6, which extend inwardly into the casing to eject ajet of water or air against a wheel 7.

The wheel 7 consists of a cone-shaped member having radially-disposedand longitudinally-curved blades 8, which gradually increase in breadthfrom the ends toward the center, so that the broadest portion of theblades is opposite the nozzles to provide an increased contacting'surface for the water ejected therefrom, the opposite ends of each bladelying in the same radial line. This wheel is provided with an axle 9,journaled at one end in a boss l0, formed in the wall of the conduit,and the other end of the axle 9 is journaled in a removable bearing ll,fitted in the hub 1-2 of a ring 13, which is screwed into the open end 3of the casing. To reduce the friction on the wheel 7, a suitable thrustball-bearing 14 is provided at each end thereof.

A shaft l5 is connected to the axle of the cone-wheel by a universaljoint 16, which permits the cutter to operate in curved iiues, althoughthe axle may be a continuous shaft for straight liues.

On the end of the shaft 15 are the cutters 1T, which consist of aplurality of rings having' spokes 18 and cutting-teeth 19. The upper orouter ring is of less diameter than the inner succeeding rings, so thatthe outer and smallest ring will penetrate the surface of theincrustation in the flue and the larger succeeding rings will cut deeperinto the incrustation until the whole is removed and the last andlargest ring scrapes the surface of the flue. In this way agradually-increasing cut is provided, each cutter penetrating only aportion of the incrustation, and thus the strain on each cutter and thepower required to operate them is reduced. The water which escapes fromthe open end of the casing passes into the iiue through the openingsbetween the spokes of the cutter and carries od the debris, so that themovements of parts are not obstructed.

Having thus described this invention, what I claim, and desire to secureby Letters Patent,

l. In a iuidanotor, acasing having inlet and exhaust openings, and acone-shaped member rotatably mounted in the casing and havingradially-disposed and longitudinally-curved blades, the opposite ends ofeach blade lying in the same radial line.

2. In a fluid-m otor, a casing having inlet and exhaust openings, and acone-shaped member rotatably mounted in the casing and havingradially-disposed and longitudinally-curved blades that graduallyincrease in breadth from IOO the ends toward the center, the oppositeends of each blade lying in the same radial line.

3. In a device of the class described the combination of a casing havinga closed end and an open end, a cone-shaped member rotatably mounted inthe casing and having radially disposed and longitudinally curvedblades, broadest midway their' ends, and a conduit formed in the closedend of the casing, said conduit terminating' in nozzles arranged todirect the impact of the fluid against the broadest portion of theblades.

4. A fluid-actuated motor comprising a casing, a rotary driven membertherein having curved blades on its periphery, and kalongitudinally-disposed conduit terminating in nozzles that projectinwardly from opposite sides of the casing toward opposite sides of therotary driven member.

5. In a device of the class described, the combination of a cylindricalcasing having an open end and a closed end provided vwith an approximatesemicircular conduit disposed longitudinally of the casing, said conduitterminating in inwardly-directed nozzles, a coneshaped member mounted inthe casing with l its smaller end journaled in the closed end of thecasing and provided with longitudinally- Vpresence of two witnesses.
